Especially for some sites, such as the Washington Post, when attempting to clear Focus by tapping the trash can, Focus freezes, then (both) the iPad or iPhone go black with a small spinning circle, rebooting to iPad's/iPhone's entry screen. This started happening recently, in early 2023, after updating iOS. Very very very (did I say "very"?) annoying. If this is not a current Focus bug report, it should be.
